IRIBARREN-ALFONSO, Augusto; LOPEZ-MARZO, Adaris  and  LABRADA-RODRIGUEZ, Ángel. Formation of cobalt and hydrogen phosphate-based flower-like structures: Influence of polyvinyl alcohol and pyrazole. Rev Cub Quim [online]. 2018, vol.30, n.1, pp. 45-54. ISSN 2224-5421.

Phosphate compounds have been object of studies due to their possibilities to be used in catalyst, optoelectronics and optics among other applications. Cobalt and hydrogen phosphate-based radiating sprays of acicular flower-like structures with petals of about 100-300 nm cross-sections were obtained by chemical synthesis. The use of polyvinyl alcohol and pyrazole in the initial dissolutions showed their influences in the variation of size and characteristics of the obtained flower-like structures. In this case the flower petals become more acute, which leads the increasing the specific surface and it facilitates to coat and impregnate the structures with other substance in order to form heterostructures.

Keywords : cobalt phosphate; flower-like structures; chemical synthesis.
